To ctZZ whom, t yimg/concern:

Be it known that I, HENRY FSHEPHABD, a citizen of the United States, and a' Aresident of the city of New York, borough of Brook,- lyn, in the county of Kings and State of New York, have invented a new and lImproved Dumping-Vehicle, of which the following is a full, clear, and exact description; Y.

This invention relates to improvements in dumping wagons or trucks; and the object is to provide a vehicle with an inclined bed` frame down which 'when released the body will slide by gravity to dumping position, and, further, to provide a simple means for releasing the tail-board from the body while dumping.

Other-objectsoff the invention will appear in the general description.

I will describe a dumping vehic1e embodyf ing my invention and then point out the novel features in the appended claims.

Reference is to be had to the'accompanying drawings, forming a part of this specification,- in which similar characters of, reference indii cate corresponding parts in all the figures.

Figure 1 is aplan view of adumping-vehicle embodying my invention. Fig. 2 is aside elevation thereof. Fig. 3 is a side,elevatiori showing the body in dumpingposition. Figi Fig. 5 is a section on the line 'y y of Fig. 2, and Fig. 6 is a perspective view of a releasing-lever ein'T ployed. J

The bed-frame of the vehicle comprisesth side rails 1, supported on the' axles '2:3 'by means of the front springs 4 and the rear springs 5.` The side rails 1 'are connected by afront cross-bar 6, a rear cross-bar?, anda center cross-bar 8. The frontendsv of the springs 5 are connected in the usual manner to the cross-bar 8, but' the rear portions'of the springs are' connected'to the lower ends of links 9, the upper: ends of 'which have swinging connection with the cross-bar 7. It will be noted .that .the links 9 are inclined downward and rearward, so as to form buffers for the body of the vehicle while dumping, as will be hereinafter described.

The bed-frame is inclined rearward and downward,l and mounted to slide on the bedframe is the body 10, which may be made of metal or wood, and in the case of wood I preferably provide it with a lining 11 of metal, such as sheet-iron. It will be noted that at the junction of the bot-tom of the lining and the sides and ends the metal is curved, as indicated at 12.- This lining is curved in the manner described instead of making square joints, because I find that by so curving the parts hot asphalt or similar material will .morereadily separate itself from the metal in dumping.

Secured to the bottom of the body is a cross-bar 12a, having journals 13 extended from its ends, and on these journals are mounted rollers 14, which are movable on the rear portion of the side rails 1, and the top of the side rails may be provided with metal plates 15, so as to prevent'undue wear. These rollers 14 are provided with annular lianges on their.outer ends to engage against the 'outer surface ofthe' side rails, so as to pre- Lvent' lateral movement, and `it will be noted that the;forward.portions of the side rails haveraised parts 16, the upper surfaces of which are substantially on a line with the tops of the rollers 14. These raised surfaces 16'are designed to support the front portion4 of the body when the said body is in its normal position, as indicated in Fig. 2, and weartions.

]Keeper-bars 18 are attached at their ends plates 17 may be placed on these raised portothe side rails 1 and extend over and parfallel with the bearing-surface of the said side rails, along which the rollers move. These .keeper-bars at their rear ends will prevent the rollers from moving od the side rails and their upper portions will vprevent upward movements of therollers, and consequently `r'prevent upward movement of the body. The

said keeper-bars,- as shown in Fig. 2, engage with Vtheljange portions of the rollers.

' Tailboard-supporting bars, consisting of i TOO tail-board-holding bars engage. The portions 2O of the tail-board-supporting bars are movable or held from lateral movement in guides 22, attached to the sides of the body 10, and the ends of these portions 2O are provided with hooks 23 to engage in eyes 24, attached to the ends of the tail-board near the top'.

The tail-board consists of two sections 25 and 26, hinged together at the outer side. The object ot' this is tol permit the body of the vehicle to readily pass along the inner side of the tail-board when the said body is moved to its normal position-that is, the rear ends of the sides of the body are curvedand when the body is tilted downward to a position to be slid yupward on the bed-frame the said curved ends will engage with the lower section 26 of the tail-board, readily swinging it outward, and then the said section will move inward again against the end of the body, and the tail-board will be locked in this position by means of hooks 27, mounted toswing on the sides of the body. Pins 2S on the ends of the section 26 of the tailboard when the tail-board is moved to its closing position will engage the upper curved edge of the hooks, swinging the hooks downward until the said pins pass into engagement with the shoulders of the hooks, when the opposite longer weighted ends 29 will move the hooks to locking position. These ends 29 are held from moving too far downward by means of pins 30 on the body, and they are prevented from moving too far upward by means of pins 31 on the body. When the body is in normal position, the ends or extensions 29 engagefin loops 29a on the bars 18, and the length forward of the loops is about equal to the distance between the center of the rollers 1 4 and a vertical line from p the center of the rear axle, so that the extensions will clear the loops when the rollers reach said vertical line from the axle, at which point the body begins to tilt.

Mounted to swing, as here shown, in a board 32, connected to the seat-uprights 33, isa locking latch or hook 34, designed to hold the body in its normal position by engaging with a part carried by the said body. This part consists of a roller 35, mountedin hangers 36, attached to the bottom of the body, and as the body is slid upward to its normal position the said roller will engage with the curved surface at the end of the latch, moving the latch upward 'until the roller passes to the hook portion of the latch. As a means for lifting the latch I employ a lever 37, which is here shown as mounted to swing on one of the seat-uprights 33. This lever passes underneath the latch, and preferably it is connected to the latch by means of a link 38, the said link passing through a slot in the latch. By this con- -j' struction the lever not only serves as a means for lifting the latch, but it serves as an extra weight to hold the latch in locking position, thus preventing it from becoming disengaged from the roller when the vehicle is in motion.

Extended rearward from the front'portion of the bed-frame is a retarding-bar 39. This retarding-bar is designed to engage on the upper surface of the roller-35 between the hangers 36 and prevent the dumping of the body until the body shall have reached its rearrnost position.

In operation after releasing the latch from the roller 35 the body, with its load, will move rearward down the incline by gravity. Vhen it reaches itsdumping position, the roller 35 will become disengaged from the retardingbar 39, and then the body will tilt downward, and as the tail-board-supporting bars also move rearward, but have no swinging motion, the tail-boardwill lbe held inian upper position, the movement of the body of course moving the pins of the tail-board ontof engagement with theholding devices 27. :As the body reaches its extreme dumpingposi tion it willstrikeagainst the links 9 or against the rear ends of the springs 5, and these but' fers are provided to prevent 'any possible breaking of the bottom of the body or of the springs. After dumping the load the body is to be manually swung down upon the bedframe, and when in this positionthe tail-board will be again engaged or locked against the rear end of the body. After this the body is to be again pushed forward, and the latch 34 will automatically lock the body in this position. As a further means to prevent lateral movement'of the body relatively to the bed frame I may employ plates 40, which are attached to the side rails 1 and extend above the same to engage against the sides of the body.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
